Abstract

The unsteady N-S equations and 6dof rigid-body dynamics equations were coupled to solve on inertial coordinate system to simulate complicated unsteady flows with moving boundary, moving chimera grids were adopted and dual time stepping approach joined with explicit four stage Runge-Kutta method were used for computation. In order to verify the efficiency of the present method, unsteady flows about an oscillating rectangular wing and release of store were simulated. The computational results are in good agreement with experiment date from other literatures ·

Key words： dual-time stepping method; moving chimera grid; multi-body relative motion; unsteady N-S equation
